This article describes known issues for running NeoOffice on macOS 10.12 Sierra, 10.13 High Sierra, 10.14 Mojave, 10.15 Catalina. Follow us on Twitter @NeoOffice to get notified when we fix any Sierra, High Sierra, Mojave, or Catalina issues.

[edit]Problems after upgrading to Sierra, High Sierra, Mojave, or Catalina?

If you see the dialog shown in the screen snapshot to the right when you edit or try to save a document, then the problem is that you have launched NeoOffice Viewer. NeoOffice Viewer can only view files and cannot save documents.

To fix this problem, right-click or Control-click on the NeoOffice icon in the Dock while NeoOffice Viewer is still running. In the popup menu that appears, select the Options > Show in Finder menu item. A Finder window will appear. Quit NeoOffice, drag the NeoOffice application in that Finder window to the Trash, and empty the Trash.

If you have not already installed NeoOffice Professional Edition or Classic Edition or NeoOffice from the Mac App Store, install either now using the steps in Step 1 above.

[edit]Step 3 - If NeoOffice tells you to install a newer version, try these steps

If your web browser displays a page telling you to install a newer version of NeoOffice whenever you launch NeoOffice, then you have an old version of NeoOffice Professional Edition or Classic Edition installed on your machine.

To fix this problem, right-click or Control-click on the NeoOffice icon in the Dock while NeoOffice is still running. In the popup menu that appears, select the Options > Show in Finder menu item. A Finder window will appear. Quit NeoOffice, drag the NeoOffice application in that Finder window to the Trash, and empty the Trash.

If you have not already installed NeoOffice Professional Edition or Classic Edition or NeoOffice from the Mac App Store, install either now using the steps in Step 1 above.

[edit]Step 4 - If the Mac App Store tells you that NeoOffice is already installed, try these steps

If Apple's App Store application displays a dialog that says that NeoOffice is already installed, then you have an old version of NeoOffice Professional Edition or Classic Edition installed on your machine.

To fix this problem, open a Finder window and go to the /Applications folder. Drag the NeoOffice application in that Finder window to the Trash, and empty the Trash. Then, go back to Apple's App Store application and click on the download icon to install NeoOffice.
